li/z'inesses;

Be it Rnownthat I JoHnlVristEli BAT- pony, a citizen of the .United States, residingat San Jose, in the (county ofSanta Clara and State" of California, have invent.

eda new and usefullmprovement in Airships, of whichthe following is a specification. j

My; invention :relates to improveinents in airships, and the objects of my invention arer- 1 stto so construct a mechanically driven airship which-will not only navigate, in theair, butalse on. land or on watergas-the occasion requires. 2nd-.to,con-

- pressure in the ,path. of travel, thereby structan airship-that will divert the air nging thehead resistance of the air to a minimum. I attain theseobjects by the meanslof the appliences illustrated in the mompany-ing drawings, 1n whieh 1 is a cross section view on the line of ..A++A,,Fig.2. Fig. 2 is averticalaxial section, and F i 3 is a detailview showing the method of uttoning the'sections .of the covering.

.In the drawings similar numerals refer to similar parts.

My invention consists of an elongated bag or frame 1 running to a point at bo'th prow and st m, and is cqnstructedof suitable mph terial. The covering thereof is made 1n sections buttoned together, as shown at Fig.

3, so that any section can be easily removed. There is a cabin, 3 Fig. '2, at the lower central partof said bag or frame, and the door leading into the c'abin is shown at 4; the sides of the cabin follow the contour of the bag, and the ends of the cabin are inclosed within the bag. On the top of the frame, half way between the prowand the stern, I have located an observation bridge 5, Fig.

'2, with a passage-way 6 running thereto from the cabin. The floor of the bridge is attached to the top'of the bag, and the floor of the-cabin is laid within the bag, each having a level surface. Running from both the prow and the stern through said bag cen-.

trally, and terminating in the end walls of the cabin, near the ceiling thereof, are hollow cores 8. Attached to these cores and extending outward with the opposite ends thereof attached to the inner side of the bag or frame, as shown at 10 are arms 11, Fig. 2, arranged .equi-distant from each other within the circumference of the, bag.

, These arms new hold the bag iirshape and to give: 1t .the proper rlgidltyd [prefer to arrange these armsin groups of four with 'a sufficient number ofthese' groups to ac-' .complish the purpose desired.

i 'iroHNwEsL-EY BATDQRF. or shit ess, onmrotsuia My airship -is .here presented with four 'planes,-shown at l2atth'e'sides of the bag,

, working in pairs, two toward the stern and two toward the prow of: the bag. "Thereis a rod. 13 eonnectmg each of saulfpairs at their centers. ...Tl1ls rod runsthrough the f center of the 'bag and throughcore Syand' bears upon. the:upper:surface' of arms 11."

These planeszcan be turned at any angle by means of shafts providedwith bevel gears operated by wheels sho\vn'at14-I ig'. 2. The pair of planes towartbtlie"stern[are -oper- .ated by shafts "15 and '16:connected by hotel gears 17, and. by. bevel gears 12) Upnnecting shafts 1(3 audw18- and the beve'hgear 520 at the opposite-endof. shaft 18 turnsthe planes onrod 13. v .'lll1e plane's toward the pl-ow are operated by .1heans;of shafts-21" and 22 mm nected by bevel .gears'i23, theplane's being turned by bevel gearse2+l-*connecting shaft 22 and r0d-13.: Yoke 9, Fig. 2,.'-e'xtends'.'

along the ceilingof the "eabin,'and* shafts 18 and-22 have their hearings in opposite ends of said yoke.

Pivoted beavelifl oas which are attached to and run backward from both the top and the bottom of the frame,'is a rudder 26, controlled by a lever rod 27 attached at the bottom of 'pivot rod 28, as shown at Fig. 2. Rod 27 extends forward to the operators station at the prow of the boat, who operates the rudder by means of lever 29.

Extending over the ba are two altitude propellers 30, one at a dlstance from each end of the observation bridge 5, and between the rudder and the rear end of the bag is the rear propeller 31. Eellers are rotated by means of shafts and evel ears, as follows'z-The pro when 30 towar the stern is rotated by beve gem. 32, and shaft 33. Shaft 33 is broken and is thrown in and out by means of rluteh 36 operated by lever 13?. Propeller 30 toward the prow is rotated by bevel gear 38, and shaft 39. Shaft. 39 is broken and is thrown in and out by means of clutch 42 operated by lever 43. Rear propeller 31 is rotated by bevel gears 32, shaft 33 and bevel gears These proshaft 4.4 running -backward through core 8. The propeller 31- is rigidly attached to shaft44.

Arranged at the front end of the bag or frame is an air diverter 46. "It consists of a cone with spiral blades starting at the point of the cone and encircling the same vrrom the point to the base, as shown at Figs. 1 and2. The object of this diverter is'tobreak up the currents. of air in the path of the ship. It also forces the air backward and ineloses the craftin a cylindrical envelop of air, making astable atmosphere about the ship, with a decided rear pressure brought about by the diverted air closing in to form a normal atmosphere. Divertei' 4G is rigidly attached to the end of shaft- 47 running through core 8 with roller bearings in the nose of the bag, as shown at 48. Shaft 47 is driven by bevel gears 38, shaft 39 and bevel gears and 41, Fig. 2.

Under the bag, located at the center thereof, is a boat, shown at 49, Fig. 2. This boat is mechanically driven, and is adapted lobe used in' case navigation in water is necessary or desirable. The engine is located in the boat, as shown at 50 Fig. 2. The operator is stationed at the prow of the boat, and there is an observation window locatedin the prow shown at 51. The en- 1 gineer is located in the stern of the boat.

The rudder of the boat is shown at 52 pivoted between rods 5353, and operated by rod 54 and lever 55. ,The propeller of the boat is shown at 56 between the rudder and the stern'of the boat and is rotated on a shaft running directly from the engine.

In case it is necessary or desirable to naviis shown at 64 Fig. 3 ready to .be buttoned in place; buttons 65 being turned parallel to button holes 68.

Having thus described my invention what I claim and desire to secure by. Letters Pat-- ent isv An airship comprising an elongated rigid frame, tapering to a pointat each end thereof, a cabinwithin said frame, hollow cores extending from said cabin in opposite direc provided my airship tions through the center of said frame to the prow and stern thereof, a shaft in each of said cores, a propeller attached to the shaft at the stern and means for rotating I the same, a rudder, a distance beyond said propeller, connected to said frame .at the stern thereof, an air diverter, Wit-h spiral blades encircling the same, revoluble around the tapering point at the prow, said diverter beingattached to the shaft in the core, means for rotating said diverter, anda boat member provided with wheels below said frame and rigidly and snugly attached thereto.
